When was Bill Clinton a lame duck?

Bill Clinton was considered a lame duck president after the midterm elections in November 1998, when the Republican Party gained significant seats in Congress. His status as a lame duck was further solidified after the House of Representatives impeached him in December 1998, although he was acquitted by the Senate in February 1999. During this period, he had limited political capital and influence, as he was nearing the end of his second term, which concluded in January 2001.
